TF-MCA Yopanda Halogen ya Lawi Yoletsa Moto ya Melamine Cyanurate (MCA)
Chiyambi
Melamine Cyanurate (MCA) ndi chinthu choletsa moto chomwe chili ndi nayitrogeni chomwe chimagwira ntchito bwino kwambiri popanga zinthu zopangidwa ndi pulasitiki. Chimagwiritsidwa ntchito kwambiri mumakampani opanga mapulasitiki ngati choletsa moto.
Pambuyo poyamwa kutentha ndi kutentha kwambiri, MCA imasungunuka kukhala nayitrogeni, madzi, carbon dioxide ndi mpweya wina womwe umachotsa kutentha kwa reactant kuti ukwaniritse cholinga cha lawi loletsa moto. Chifukwa cha kutentha kwakukulu kwa sublimation komanso kukhazikika kwa kutentha, MCA ingagwiritsidwe ntchito pokonza utomoni wambiri.

Makhalidwe
MCA ndi mankhwala oletsa moto amphamvu kwambiri chifukwa cha kuchuluka kwa nayitrogeni, zomwe zimapangitsa kuti ikhale chisankho chabwino kwambiri pa zinthu zomwe sizimayaka kwambiri. Kukhazikika kwake pa kutentha, kuphatikiza ndi poizoni wake wochepa, kumapangitsa kuti ikhale njira yotchuka m'malo mwa mankhwala ena oletsa moto omwe amagwiritsidwa ntchito kwambiri monga mankhwala opangidwa ndi brominated. Kuphatikiza apo, MCA ndi yotsika mtengo komanso yosavuta kupanga, zomwe zimapangitsa kuti ikhale chisankho chotsika mtengo pa ntchito zazikulu.
Kugwiritsa ntchito
MCA imagwiritsidwa ntchito ngati choletsa moto m'zinthu zosiyanasiyana, kuphatikizapo ma polyamides, ma polyurethane, ma polyester, ndi ma epoxy resins. Ndi yothandiza kwambiri m'mapulasitiki opanga zinthu, omwe amafunika kutentha kwambiri komanso osayaka kwambiri. MCA ingagwiritsidwenso ntchito mu nsalu, utoto, ndi zokutira kuti iwonjezere kukana kwa moto. Mumakampani omanga, MCA ikhoza kuwonjezeredwa ku zipangizo zomangira monga kutchinjiriza thovu kuti ichepetse kufalikira kwa moto.
Kuwonjezera pa kugwiritsidwa ntchito kwake ngati choletsa moto, MCA ilinso ndi ntchito zina. Ingagwiritsidwe ntchito ngati chochiritsira ma epoxies, ndipo yawonetsedwa kuti ndi yothandiza pochepetsa kuchuluka kwa utsi womwe umatuluka panthawi yamoto, zomwe zimapangitsa kuti ikhale gawo lofunika kwambiri pazinthu zoletsa moto.
